摘　　要：根据PHC管桩强度高、穿越土层的能力强等特点,针对PHC管桩进入岩层后,经过强烈的挤压,岩土承载力提高的现象,通过对多根试桩试验结果和有关PHC管桩应力实测数据进行分析和总结,提出了岩土的极限侧阻力和端阻力标准值的参考值,并结合工程实例进行了经济分析。Based on the fact that PHC concrete pipe piles with high strength and powerful penetration can increase the load bearing capacity of rock and soil after they subject to strong squeezing in rock layers, in the paper the reference data of ultimate lateral resistance and point resistance of rock and soil has been given out and the economic analysis made for practical engineering projects on the basis of the analysis and summary from the experimental results of several pipe piles and the measured stress data of PHC concrete pipe piles.
